Proto-board Z80 computer

diy_zilog

We’ve seenĀ  Z80 processor based computers before but they usually use a printed circuit board to easily and reliably connect all the components. [Marton] sent us his Z80 based computer from a while back that is built entirely on prototyping board. He made his own video board that utilizes a TV as the monitor and his own mainboard incorporating a keyboard controller. The system runs at 4 MHz, has 32k of ram, and runs [Marton’s] own system software which he has posted. Its quite impressive and we love the protoboard porn with thousands of grey wires running everywhere.

[Marton] used the resources on [Hans Summers’] site for his project. Make sure to check it out if you’re interested in a broader background concerning DIY Zilog Z80 computers.

  1. seriously they finally post something worth while and you make an arduino joke. Plus the z80 is way better than the arduino anyway. :P

  2. @ nave.notnilc
    It probably could run CP/M with a little bit of tweakery, although it could really do with 64k to do it comfortably – especially if it’s going to be networked.
    I still miss my old TRS80/II that ran something very similar to CP/M on a z80 with 64k…

  3. Ahh, the memories… Did this with a Z80A when I was 13 years old on a blue 22/44 protoboard using bits of 25-pair telco wire, so mine was much more colorful… :)
